I would say the hard problem of consciousness is the problem of relativity. How do you see what happens in a different reference frame? Well, you can speculate, model, imagine it, but you can't see it. To see it you must be in that reference frame an look right from there. When you're in place of mind, you see what happens in it, otherwise you don't and can only speculate, model and imagine.
